Magnus sighed rubbing his eyes even if it would mess up his eyeliner. He was tired, his client of the day had been a very demanding mundane who wanted to summon a demon to haunt her ex, and he was still waiting for his shadowhunter boyfriend.

He looked at the clock in the study. 2:49 in the morning. And Alec still wasn't home. He knew how late his love could be out, but still, not even a text or a phone call. He got up for maybe the fourth time for a cup of coffee.

Was it so hard for him to just send him a text message? A 'hey I'm alive?' or a 'don't stay up I'll be home late?' Alec had informed him all he had scheduled that evening was routine recon so why was he so late?

He sighed, tightened the sash on his golden sleeping gown, and sat down on his plush chair in the living room. He added a swig of alcohol to his coffee and waited some more.

Magnus awoke to the sound of the shower running, he didn't know when he had fallen asleep and hadn't noticed when Alec had snuck in. And lets be honest, he HAD snuck in, and headed straight for the shower. It was 430 in the morning when Alec finally came out of the bathroom a towel wrapped around his waist.

"Hello Alexander" purred Magnus hugging close against him and nibbling his ear.

"Hey Mags" he replied a heat building up across his cheeks. He hated yet also LOVED every time Magnus breathed his name and made him blush.

Magnus looked at his boyfriend's chest lovingly, who could blame him, the children of the Angel were all gorgeous, but he like to think that maybe God himself had sculpted the greatness that was Alec Lightwood's abs. He stopped suddenly. He had barely noticed it. Scratches on his chest right under his collar bone.

"What happened?" he asked reaching across and touching the strange marks.

Alec flinched back "nothing!" he stammered before practically running into the bedroom. Magnus thought it odd, but was too tired to question it further.

He went to the bedroom and crawled into bed, he watched as Alec got dressed and strangely put on a muscle shirt. Strange, he thought, Alec always slept shirtless.

The alarm went off horribly early as Magnus reached over to stroke Alec's arm and was incredibly disappointed when the bed was empty.

He got out of bed a pout on his lips. Late night and now an early morning, would he ever see his boyfriend?

This happened for 3 more days as Magnus sulked. He didn't want to think about it, but for all those days Alec had been acting strange, constantly ran straight to the shower, and try as he might to hide it he had more scratches on his chest and even some on his arms and just last night he had heard a strange phonecall between him and Isabelle.

"I know she's crying, I don't know Iz cant you comfort her? I'll be back tomorrow for her"

When asked about the conversation the shadowhunter had denied it and explained to Magnus maybe he had just misheard him.

And then early in the morning another phone call. "Iz no! I'll take care of it, no don't tell Magnus! I'll tell him myself. He deserves me telling him. Izzy, I promise, I'll tell him! I just need more time"

Magnus had enough, he didn't know exactly what was going on but he was drawing the line today!

Heartbroken, he loved his Alexander more than anything, but he knew he deserved so much more than someone unfaithful. He walked out to the living room to confront him, but sadly, he was already gone.

The hours passed as Magnus waited in his chair. Chairman Meow in his lap as he stroked the cat melancholy of what was going on in his life.

"How could he do this to me?" he cried to the cat who yawned. "how do you not see the emergency in this??"

He scrunched the cats face between his hands "you are of no help! No cream for you" The cats ears perked up "oh, now you care."

He continued to sit angrily waiting for another hour and still nothing, and that's when the warlock snapped.

Love of his life or not, NOBODY cheated on Magnus Bane, High Warlock of Brooklyn.

He marched his magnificent self into their shared bedroom and grabbed some of the shadowhunters clothes, he picked out Alec's favorite holy sweater, the stupid leather jacket he swore his life on and his favorite boxers that he always wore when it was fresh out the dryer, and he marched his way back to the living room and tossed things straight into the burning fireplace one at a time.

He had just thrown in the leather jacket when he heard familiar sound of keys at the door.

"Mags! Magnus?" Alec asked nervously upon entering the loft. "I need to talk to you about something important"

"Well well Alexander" started the warlock a cup of alcohol in his hands and murder in his eyes. "look who's home."

"Alexander, I love you. You don't understand how much I love you, but how could you!" He yelled sadly, the sound of heartbreak in the air.

"I love you too?" Alec asked confused but his eyes shot open when he caught the end. "you know?? Did Izzy tell you?"

"NO! She didn't but I cant believe you didn't."

"I know Mags, but please understand, she was just so cute, and defenseless. She NEEDED me!" He protested.

"Alexander I needed you! I cant believe you, for some girl! You're willing to lose me for just some random girl!"

"Magnus, she would have died without me! I'm sorry!"

"Oh don't be dramatic! I'm sure the little hussy would not have DIED without you! Do you really think I am that dumb! 400 years Alexander! 400! I was not born yesterday"

"Magnus, I'm sorry" Alec moved in closer reaching out to Magnus but he had moved away.

"No, I don't care, no matter what you say, I will NEVER forgive you" cried Magnus.

"Mags, I'm sorry, I KNOW you are a one cat kind of man, but you'll love her! She's tiny, and I got rid of all the fleas! She's been bathed and I taught her how to use the litter! Yeah she scratches, but she's learning!" The words rushed out as he tried to explain.

"ALEXANDER! STOP YOU DON'T UNDERSTAN-" He stopped dead in his tracks. "wait what?"

With that the dark haired boy reached inside his jacket and pulled out the little white bundle of fur.

"Here, look! I know I should have asked, but she was just so small"

Magnus burst into a hysterics of laughs and tears as he threw himself into Alec's arms.

"A kitten! It was just a kitten!" He finally managed in between his crying

"uh yeah, a kitten, I named her Lilo can we keep her?" he pleaded with his bright blue eyes

"Of course it's a kitten! Of course! Yes we can keep her! "

"Magnus, why are you crying? What did you think it was?"

"I thought you were cheating!"

Alec placed the small cat on the floor and grabbed his boyfriend pulling him close.

"Magnus, I love you, more than anything. I would never EVER cheat on you. Please understand that, for all my life, I will only ever have eyes for you."

Just like that, the world seemed perfect again, he hugged his darling close as the small cat rubbed lovingly against his legs.

Everything was perfect until:

"Hey Magnus, what is that burning smell?"
